Anastomat for closing surgical incision

Abstract

The invention discloses an anastomat for closing surgical incision. The anastomat comprises a firing mechanism and an endoscopic stapler cartridge transmitting mechanism connected to the firing mechanism, wherein the endoscopic stapler cartridge transmitting mechanism comprises an endoscopic stapler cartridge guiding groove, a strip guiding part and an endoscopic stapler cartridge ejecting plate;an operation part for controlling opening and closing is arranged at the rear end of the strip guiding part; a pair of bearing lugs, which faces the corresponding directions of the endoscopic staplercartridge guiding groove and the operation part, is arranged at the endoscopic stapler cartridge guiding groove and the operation part in a bulging manner; the bearing lugs and a pin shaft are used for combining the endoscopic stapler cartridge guiding groove and the strip guiding part, a spiral spring is packed and penetrates through the pin shaft on the bearing lug, and the spiral spring is usedfor enabling the strip guiding part to be biased towards the direction that the strip guiding part and the endoscopic stapler cartridge guiding groove are in normalcy mutual closing; a chute part which is bulged towards the direction of the endoscopic stapler cartridge guiding groove is arranged at the middle of the strip guiding part, the width of the chute part is equal to the internal spacingof two endoscopic stapler cartridge feet of an endoscopic stapler cartridge, the upper surface of the chute part and the endoscopic stapler cartridge crown of the endoscopic stapler cartridge are in sliding cooperation, the outside surface of the chute part and the upper segment of the endoscopic stapler cartridge are in sliding cooperation, the endoscopic stapler cartridge ejecting plate and thechute part are in sliding cooperation, and the endoscopic stapler cartridge is easy to disinfect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a stapler for closing surgical incisions. Background technique [0002] Skin anastomosis (suture) stapler is a medical device for suturing human epidermal wounds to promote wound healing and postoperative wounds without removing stitches. , nail pushing piece and return spring, etc. During operation, align the nail outlet of the skin anastomotic (suture) stapler with the suturing site, press down the moving handle, and make the staples in the staple magazine meet resistance and form on the wound, so that The open wound is closed to achieve the purpose of suturing. It is suitable for superficial skin suture of human trauma and surgical incision and patch fixation for abdominal hernia repair. The principle of skin stapler is similar to that of a stapler. It has simple operation, fast suturing speed, With the advantages of good postoperative incision healing, it is the ...

Problems solved by technology

[0003] However, the existing staplers require the operator to press the handle to fix the staples on the wound, which is time-consuming and labor-intensive. During the operation, the staples will be stuck in the staple opening due to the insufficient force used by the operator. , resulting in damage to the stapler, causing secondary damage to the wound at the same time, and prolonging the operation time. When different patients are treated, different striking strengths are sometimes required to avoid secondary damage to the wound by the stapler, such as suturing children's wounds Because the outermost stratum corneum of the skin is thin, the staples are easy to drive in, while the stratum corneum of adults is thicker and requires greater striking force. Therefore, it is necessary to adjust the strength of firing the staples to adapt to the For patients with different body surface skin characteristics, the staple cartridge in the prior art is in a closed type, and it is difficult to disinfect it
